You bet that there are going to be knock-offs. GYCB is one of the best companies out there, and almost all of their lures have knock-offs. GYCB is the king of getting knocked-off. LOL
Depending on what all lengths they produce, I would really like to see a 2 or 3" model, which I would use as a jig trailer. It could be an interesting twist on the old stand-by. It would also be a different version that bass might not have seen, and they would be more willing to strike it.
